The Relationship Between Personality and Job Attribute Preferences
This item is only available electronically.The success of an organisation is contingent upon the attraction of highly talented individuals. Thus, in order to differentiate themselves from their competitors, organisations must offer such individuals a rewards package that they find attractive. The limited literature on this topic has identified various relationships between job attribute preferences and personality traits. However, only weak relationships have been established between these concepts, and there is evidence to suggest that this is related to the bandwidth-fidelity problem. Some authors argue that the solution to this problem is to test personality at the facet level, which would provide more analytical and predictive power. This also allows for the possibility of facets within a particular trait exerting countervailing effects upon job attribute preferences, which might otherwise obscure trait level relationships. The present study aimed to investigate these ideas through an online survey assessing the personality and job attribute preferences of 143 first-year psychology students at the University of Adelaide. Multiple hierarchical regression was used to control for various demographic variables, before Akaike’s Information Criterion was utilised to compare the predictive power of personality traits to their respective facets within the Five-Factor Model of personality. The results indicated not only that personality is related to job attribute preferences, but that facets can predict in opposite directions and thus improve analytical power in some circumstances. These findings have implications for improving the validity of personality testing in recruitment settings, and for further research on how organisations can attract applicants with particular personality characteristics.Thesis (B.PsychSc(Hons)) -- University of Adelaide, School of Psychology, 201
ISS Ammonia Leak Detection Through X-Ray Fluorescence
Ammonia leaks are a significant concern for the International Space Station (ISS). The ISS has external transport lines that direct liquid ammonia to radiator panels where the ammonia is cooled and then brought back to thermal control units. These transport lines and radiator panels are subject to stress from micrometeorites and temperature variations, and have developed small leaks. The ISS can accommodate these leaks at their present rate, but if the rate increased by a factor of ten, it could potentially deplete the ammonia supply and impact the proper functioning of the ISS thermal control system, causing a serious safety risk. A proposed ISS astrophysics instrument, the Lobster X-Ray Monitor, can be used to detect and localize ISS ammonia leaks. Based on the optical design of the eye of its namesake crustacean, the Lobster detector gives simultaneously large field of view and good position resolution. The leak detection principle is that the nitrogen in the leaking ammonia will be ionized by X-rays from the Sun, and then emit its own characteristic Xray signal. The Lobster instrument, nominally facing zenith for its astrophysics observations, can be periodically pointed towards the ISS radiator panels and some sections of the transport lines to detect and localize the characteristic X-rays from the ammonia leaks. Another possibility is to use the ISS robot arm to grab the Lobster instrument and scan it across the transport lines and radiator panels. In this case the leak detection can be made more sensitive by including a focused 100-microampere electron beam to stimulate X-ray emission from the leaking nitrogen. Laboratory studies have shown that either approach can be used to locate ammonia leaks at the level of 0.1 kg/day, a threshold rate of concern for the ISS. The Lobster instrument uses two main components: (1) a microchannel plate optic (also known as a Lobster optic) that focuses the X-rays and directs them to the focal plane, and (2) a CCD (charge coupled device) focal plane detector that reads out the position and energy of the X-rays, allowing a determination of the leak location. The effective area of the detection system is approximately 2 cm(exp2) at 1 keV. The Lobster astrophysics instrument, designed for monitoring the sky for Xray transients, gives high sensitivity along with large field of view (3030deg) and good spatial resolution (1 arc min). This offers a significant benefit for detecting ISS ammonia leaks, since the goal is to localize small leaks as efficiently as possible
Developing and Implementing an Accessible, Touch-based Web App for Inclusive Learning
With the prevalence of mobile devices and platforms used throughout the world and the increasing number of organizations with mobile versions of their web sites, it is essential that those applications and sites are accessible, usable and flexible. This project involved the inclusive development and iterative evaluation of a platform-independent, web-based learning app. Usability testing with students, faculty, and individuals with disabilities were combined with manual accessibility evaluations to ensure that a wide range of users and devices would be able to benefit from the structure of such an application. The results of this project detail the process of creating a flexible, platform-independent mobile learning app as well as some of the broader benefits that can result from accessibility and usability improvements to a mobile application. The resulting prototype has been implemented in a “live” environment at a non-profit organization that serves individuals with disabilities
Processing CCD Images to Detect Transits of Earth-Sized Planets: Maximizing Sensitivity While Achieving Reasonable Downlink Requirements
We have performed end-to-end laboratory and numerical simulations to demonstrate the capability of differential photometry under realistic operating conditions to detect transits of Earth-sized planets orbiting solar-like stars. Data acquisition and processing were conducted using the same methods planned for the proposed Kepler Mission. These included performing aperture photometry on large-format CCD images of an artificial star fields obtained without a shutter at a readout rate of 1 megapixel/sec, detecting and removing cosmic rays from individual exposures and making the necessary corrections for nonlinearity and shutterless operation in the absence of darks. We will discuss the image processing tasks performed `on-board' the simulated spacecraft, which yielded raw photometry and ancillary data used to monitor and correct for systematic effects, and the data processing and analysis tasks conducted to obtain lightcurves from the raw data and characterize the detectability of transits. The laboratory results are discussed along with the results of a numerical simulation carried out in parallel with the laboratory simulation. These two simulations demonstrate that a system-level differential photometric precision of 10-5 on five- hour intervals can be achieved under realistic conditions
Rationale and study protocol for the \u27Active Teen Leaders Avoiding Screen-time\u27 (ATLAS) group randomized controlled trial: An obesity prevention intervention for adolescent boys from schools in low-income communities
Introduction The negative consequences of unhealthy weight gain and the high likelihood of pediatric obesity tracking into adulthood highlight the importance of targeting youth who are \u27at risk\u27 of obesity. The aim of this paper is to report the rationale and study protocol for the \u27Active Teen Leaders Avoiding Screen-time\u27 (ATLAS) obesity prevention intervention for adolescent boys living in low-income communities. Methods/design The ATLAS intervention will be evaluated using a cluster randomized controlled trial in 14 secondary schools in the state of New South Wales (NSW), Australia (2012 to 2014). ATLAS is an 8-month multi-component, school-based program informed by self-determination theory and social cognitive theory. The intervention consists of teacher professional development, enhanced school-sport sessions, researcher-led seminars, lunch-time physical activity mentoring sessions, pedometers for self-monitoring, provision of equipment to schools, parental newsletters, and a smartphone application and website. Assessments were conducted at baseline and will be completed again at 9- and 18-months from baseline. Primary outcomes are body mass index (BMI) and waist circumference. Secondary outcomes include BMI z-scores, body fat (bioelectrical impedance analysis), physical activity (accelerometers), muscular fitness (grip strength and push-ups), screen-time, sugar-sweetened beverage consumption, resistance training skill competency, daytime sleepiness, subjective well-being, physical self-perception, pathological video gaming, and aggression. Hypothesized mediators of behavior change will also be explored. Discussion ATLAS is an innovative school-based intervention designed to improve the health behaviors and related outcomes of adolescent males in low-income communities

Thinking about the same things differently: Examining perceptions of a non-profit community sport organisation.
This paper explores the differing perceptions and identity responses (identification, apathy and disidentification) that potentially exist in relation to one non-profit Community Sport Organisation (CSO), and whether they explain variations in individuals’ existing values and beliefs, sport interest, community identification and views about one organisation's legitimacy. Data were collected using a quantitative online survey (n = 390), then analysed using Confirmatory Factor Analysis (CFA) and Multiple Analysis of Variance (MANOVA) to test three hypotheses investigating whether existing values and beliefs, shared community values, local players, organisational practices and sport interest varied based on perception of organisational image and identity response. Based on the contributions of this study, non-profit CSOs should spend time developing understanding of the key dimensions that make them relevant to constituents and to decipher the values and beliefs that underpin what external audiences expect from organisations. In addition, understanding specifically what a CSO's audience expects is fundamental if the organisation is to be perceived as legitimate in relation to its purpose
